OIL-BURNER.

SPECIFICATION forming part of Letters 'Patent No. 608,009, dated July 2o, lees.

Y Application filed September 13, 1897. Serial No. lfl.A (No model-.l

To all whom t may concern:

Be it known that I, AUGUSTUS W. SHANK, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvementsin Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. V

This invention relates to oil-burners especially designed'for burning kerosene-oil and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claim.

The objects of the invention are to provide a simple, efficient, and inexpensive burner which may be placed in a stove or furnace and in which the arrangeinentis'suchas to obviate pulsation, to effect a complete vaporization of the hydrocarbon fuel, to produce a strong evename, and toprovide forthe cleaning of the channels of the burner to ob'- viate the closing of said channels through the deposition of carbon. These objects are attained by the construction illustrated in the accompanying drawings, in Which- Figure l is a general view in elevatiomshowing a burner and the oil-supply tank connected therewith. Fig. 2 is an enlarged horizon-lr tal section, as on line 2 2 of Fig. l. Fig. 3 is a vertical section through the base of the burner, as on line 3 3 of Fig. 2, a portion of the stand-pipe and the T- arms at the upper end thereof being broken away to show formation of parts.

Referring to the letters of reference, A designates the body of the burner,whi ch is formed integral and preferably of cast-iron. Located Within the body of the burner is a series of vaporchannels, which comprise the outer marginal channel a and the central channel b. One end of the central channel b communicates with the outer channel a, While the opposite end thereof communicates with a closed Vit strikes With'considerable force against the C and 1n which an air-pressure 1s created to vforce the oilintothe burner.

Communicating with `the central channel ofthe burner is a stand-pipe D, which carries at its upper end a hollow T E, Whose arms project longitudinally of the burner and are provided in their under face with an aperture c for the Apassage of generated gas therefrom. Mounted upon ,said burner is a perforated hood F, Which embraces the standpipe and T and forms a confining-chamber, in which the iiame is held, the lower edge of said hood having a series of notches which form arches that rest upon the burner and admit the :llame therethrough.

In the operation of this device the oil upon the opening'of the valved is driven by the air-pressure of the tank C into the burner. Upon the entrance of the -oil into the burner l dividing-wall f, which separates the channel ot from the chamber B, whereby the oil becomes sprayed and ismore readily vaporized. It will be` understood that the .body of the burner before the oil is turned therein is heated by the application of a local iiame in any suitable manner until it has attained such a temperature as to vaporize the oil, which vapor lls the channels a and b and the chamber B. The pressure of the vapor orgas Within `the burner forces it upward through the pipe D and into the T E, from which it is discharged through the apertures c and is ignited, filling the hood F of the burner with llame. The pressure within the burner causes the gas or vapor to leave the opening c in the T with some force, so that the volume of iiame is projected downward upon the top of the burner, whereby said burner becomes intenselyheated, thereby acceleratin g the vaporization of the oil therein. Located Within the pipe C, as at e, is a check-v valve (not shown in detail, but of any suitable construction) which prevents the pressure within the burner from forcing the gas backward through said pipe.

The presence of the chamber B within the burner provides for the presence of a reserve body of gas which tends to equalize the pressure therein and obviates pulsation, causing the gas to flow steadily from the burner, producing a strong even iiame.

In the use of hydrocarbon fuels which are rich with carbon, as is kerosene, one difficulty encountered is the liability of the channels of the burner becoming closed with a deposition of carbon, rendering the burner inoperative. This difficulty is entirely obviated in my improved burner by providing for a thorough cleaning of the channels in the burner through openings communicating with said channels,which openings are closed by the screw plugs g. By removing said screw-plugs all of the channels of the burner are made accessible, so as to enable them to be readily and freely cleaned of all carbon depositions, obviating any impairing of the burners efficiency through the clogging of its vapor-channels.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

In a hydrocarbon-burner, the combination of the integral burner-body having an interior vapor-channel a traversing the four sides of said burner, a central interior vapor-channel communicating at one end with said vapor-channel a, an interior pressure-equalizing chamber communicating with the opposite end of said central channel, and the oilsupply pipe communicating with the channel a.

In testimony whereof I aflix my signature in presence of two witnesses.

AUGUSTUS W. SHANK.
